There is, in fact, not a Christian on this Earth who can be certain that Jesus even wore a beard, much less that he was born of a virgin or rose from the dead. These are just not the sort of claims that spiritual experience can authenticate.
8) Atheists believe that there is nothing beyond human life and human understanding.
Atheists are free to admit the limits of human understanding in a way that religious people are not. It is obvious that we do not fully understand the universe; but it is even more obvious that neither the Bible nor the Koran reflects our best understanding of it. We do not know whether there is complex life elsewhere in the cosmos, but there might be. If there is, such beings could have developed an understanding of nature's laws that vastly exceeds our own. Atheists can freely entertain such possibilities. They also can admit that if brilliant extraterrestrials exist, the contents of the Bible and the Koran will be even less impressive to them than they are to human atheists.
From the atheist point of view, the world's religions utterly trivialize the real beauty and immensity of the universe. One doesn't have to accept anything on insufficient evidence to make such an observation.
9) Atheists ignore the fact that religion is extremely beneficial to society.
Those who emphasize the good effects of religion never seem to realize that such effects fail to demonstrate the truth of any religious doctrine. This is why we have terms such as "wishful thinking" and "self-deception." There is a profound distinction between a consoling delusion and the truth.
In any case, the good effects of religion can surely be disputed. In most cases, it seems that religion gives people bad reasons to behave well, when good reasons are actually available. Ask yourself, which is more moral, helping the poor out of concern for their suffering, or doing so because you think the creator of the universe wants you to do it, will reward you for doing it or will punish you for not doing it?
10) Atheism provides no basis for morality.
If a person doesn't already understand that cruelty is wrong, he won't discover this by reading the Bible or the Koran — as these books are bursting with celebrations of cruelty, both human and divine. We do not get our morality from religion. We decide what is good in our good books by recourse to moral intuitions that are (at some level) hard-wired in us and that have been refined by thousands of years of thinking about the causes and possibilities of human happiness.
We have made considerable moral progress over the years, and we didn't make this progress by reading the Bible or the Koran more closely. Both books condone the practice of slavery — and yet every civilized human being now recognizes that slavery is an abomination. Whatever is good in scripture — like the golden rule — can be valued for its ethical wisdom without our believing that it was handed down to us by the creator of the universe.
